Do you mean it has a green tint over the video? I get this on rare occasions and a different player works fine. Try a different media player and see if you still have the problem.
I notice you have Intel graphics. This may, or may not, be the problem, but it is not the best solution for video editing. I also don't see any signs that QuickTime is installed. Again, may not solve the problem, but QuickTime supplies the system with lots of codecs that can be used by other applications. It's free and worth trying.
